Tanning Beds, Are they Safe?
We all like to have that healthy glow that comes from being
outdoors and getting some sun. However, we know that sun damage
can be harmful to our skin. Many turn to tanning salons to
maintain their glow, but is using a tanning bed safe?
The skin tans when exposed to ultraviolet light. To keep itself
from burning, skin will manufacture extra coloring, called
pigment. This pigment is what causes us to "tan". However, when
we get too much ultraviolet light and burn, serious problems can
occur. We may suffer damage to our eyes, early wrinkling,
blistering and rashes. At worst, we may develop certain types of
skin cancer.
Exposing your skin to the ultraviolet light of a tanning booth
is advertised as safe, though. It is now known that there are
two types of ultraviolet rays, UVA and UVB. UVB rays are the
shorter wavelengths that are most likely to cause burning.
Longer wavelength UVA rays are less likely to cause a sunburn,
but they have been shown to increase risk of melanoma.
Older style tanning beds were developed using primarily UVB
rays. These are the ones that you lay in and close on top of
your body so that the light tans both sides at once. After
publicity that the UVB rays used by these beds could be harmful,
many salons switched to devices using UVA rays. They were
thought to be safer, but current studies dispute this.
The shorter wavelength UVB rays will cause sunburn on the
outermost layer of skin. The results of overexposure are almost
immediate and very apparent. However, the UVA rays reach deeper
into the tissues, so the layers of tissue beneath the surface
can be damaged. Since the effects are harder to see, we don't
know how much damage we are doing until it's too late. Both
types of ultraviolet light are dangerous.
Continued exposure to these ultraviolet rays can make the skin
thinner and limit its ability to heal itself. Not only does this
increase premature aging and wrinkling, but it leaves the skin
more susceptible to disease, including skin cancer.
Tanning in a tanning bed can also cause retinal damage. Many
have experienced burned corneas from overuse of tanning beds,
and in extreme cases, even cataracts can develop from
overexposure. Even though customers are advised to wear eye
goggles, many make do by closing their eyes or placing a cloth
over their eyes during tanning, steps that don't stop the UV
damage to the eyes.
Are tanning beds safe? If you can limit the time that you use
them, wear goggles and be diligent, maybe. However, the best
protection is to skip the tanning bed and use a self tanner. Why
take chances with the largest organ in your body, your skin? Be
mindful of tanning, indoors or outdoors.
